Professional teeth whitening in the UK commonly costs a few hundred pounds, with the final price depending on the whitening system, the level of clinical support and the complexity of the case. At Montagu Dental, home whitening costs £650, ZOOM! in-surgery whitening costs £915, and advanced whitening costs £890. Treatment is subject to a dental assessment, and current prices should always be confirmed before you begin.
Understanding what is included matters just as much as the headline price. A professionally supervised course is planned around your teeth, your starting shade and your oral health, helping you achieve a brighter result safely and predictably.
How much does professional teeth whitening cost in the UK?
Across the UK, advertised prices for professional teeth whitening can range from around £250 to more than £1,000. Dentist-prescribed home whitening usually costs less than in-surgery treatment, while advanced cases can cost more because they require additional planning, appointments or techniques.
Fees vary between practices, so check whether a quoted price includes your consultation, custom trays, whitening gel, review appointments and any home maintenance products. A low starting price may not represent the full cost of treatment.

- ZOOM! in-surgery whitening: £915

What affects the cost of teeth whitening?
Professional teeth whitening is not a single, standard procedure. Several factors can influence the total price.
The type of whitening treatment
Dentist-prescribed home whitening uses custom-made trays and professional whitening gel. It produces gradual results and can be convenient if you prefer to whiten at your own pace.
In-surgery whitening uses a professionally applied system to produce a faster initial change. Montagu Dental offers ZOOM! whitening, followed by custom trays and professional gel to help maintain the result at home. The additional surgery time, equipment and clinical supervision make this option more expensive.
Your starting shade and the cause of discolouration
Surface staining caused by tea, coffee, red wine or smoking may respond differently from deeper discolouration. A single dark tooth, white spots or staining linked to tooth development can require advanced treatment rather than a standard whitening course.
Your dentist must identify the reason for the colour change before recommending treatment. This helps avoid spending money on an option that may not achieve the result you want.
What the quoted fee includes
A comprehensive professional whitening plan may include a dental assessment, shade recording, photographs, scans or impressions, custom trays, whitening gel and follow-up support. Ask for a clear breakdown when comparing prices between providers.
Preparation before whitening
Your teeth and gums should be healthy before whitening begins. Decay, leaking fillings or active gum problems may need attention first. Surface deposits can also make a result look uneven, so a professional dental hygiene appointment may be recommended to remove plaque, tartar and staining before treatment.
Home whitening or in-surgery whitening: which offers better value?
The best value is the treatment that suits your teeth, timescale and expectations.
Home whitening may suit you if you want gradual control over your final shade and are comfortable following a daily routine. Your reusable custom trays can also make future top-ups straightforward, provided they continue to fit correctly.
In-surgery whitening may suit you if you would like a faster initial result, perhaps before a wedding or another important event. You will still need to follow the aftercare instructions and may use home trays to maintain your shade.
Advanced whitening may be appropriate when a standard approach is unlikely to be enough. Treatment for a particularly dark tooth, complex staining or white spots needs a careful diagnosis and an individual plan.
Is professional teeth whitening worth the cost?
For suitable patients, professional whitening can be a conservative way to refresh a smile without changing the shape of the teeth or removing healthy tooth tissue. The benefits of dentist-led care include:
- An examination to check that whitening is appropriate
- A treatment plan based on the cause of discolouration
- Custom-made trays for controlled, even application
- Professional guidance if sensitivity occurs
- Advice on maintaining your result
Teeth whitening only changes the colour of natural teeth. Crowns, veneers, fillings, bridges and dentures will not whiten, so visible restorations may need to be considered when planning the final shade.
Why avoid unregulated or non-dental whitening?
In the UK, tooth whitening is legally considered dentistry. It must be provided by a registered dental professional, or by an appropriately registered dental care professional working to a dentist’s prescription.
Products or services supplied outside professional dental care may be ineffective, poorly controlled or unsuitable for your teeth. Choosing on price alone can also mean missing an underlying cause of discolouration that needs assessment.
How long do whitening results last?
Results vary according to diet, oral hygiene and habits such as smoking. Tea, coffee and red wine can gradually restain teeth. Regular cleaning, sensible aftercare and occasional top-up gel can help maintain a brighter shade.
Top-ups do not necessarily mean repeating the entire treatment. If your trays still fit correctly, your dentist may recommend additional gel and explain how to use it safely.
Frequently asked questions
Does the NHS cover teeth whitening?
Teeth whitening is normally a private cosmetic treatment rather than an NHS service. A dentist should still assess your oral health and the cause of any discolouration before treatment.
Is home whitening cheaper than in-surgery whitening?
It usually is. Home whitening requires less surgery time, while in-surgery systems involve a longer clinical appointment and specialist equipment. Compare what is included, not only the initial price.
Will professional whitening cause sensitivity?
Temporary sensitivity can occur. Your dentist can adapt the treatment, recommend suitable products and advise you on managing discomfort. Tell the practice if sensitivity is persistent or significant.
Can I whiten my crowns, veneers or fillings?
No. Whitening gel works on natural tooth tissue but does not change the shade of dental restorations. Your dentist can plan whitening around existing or proposed cosmetic work to help achieve a balanced result.
